Flat roof to roof terrace

Hi , the cost would depend on the quality of materials used either way it definitely wouldn’t come cheap! Perhaps 15k maybe. I’d advise not to live in the property at the time due to safety reasons. Don’t think you need planning permission. Hope this helps

You wud kneed to go threw building & planning regs As you’re changing the out plan of yer property.. You may not av to as different locations av different rules. Local councils is yer best bet to start with be for you even start. Cost wise cud be few grands up wards. Depends on the rules above. That depends if you can build on the flat roof??? Get as much info on it be for you start any ting& moveing yer family out. Ect”” I cud give more info if I saw yer project. Get sum 1 that nose yer works & local area rules.

Yes planning permission is needed

I’m confident we could build the subframe in advance of removing the existing roof, having the materials ready to build and have it watertight in one day, saving any weather issues. We have done this few times before now. Sunny day would be ideal. 😎 can’t see why this would need planning if you are replacing an existing roof, be a good idea to check with local planing authority & install a warm roof to conform to building control.
